Be it known that I, IRA JOHNSON, a citizen of the United States, and a resident :of Chicago, in the county of Cook and and use# of whichthe following isa specification.

The present invention relates to motor vehicles, `,and has more particular reference vto'anlmprovedl driving 'and steering mechas nism therefor.`

An object of the presentinvention is to provide a driving and steering mechanism for -niotorvehicles of and long 'type,'such andwherein the front steering carrier wheels particularly the heavy may be power "driven when desired and are power means for adjusting the steering carrieravheels vrwhen the resistance is greater than may be overcome by manual power.

A further'object of the `invention is to provide an improved fifth wheel structure admitting of the short4 turning of the truck vehicle in restricted/places, andvembody-` ingvcertain details ofthe above referred to mechanism, and which admits the use of a relatively stationaryA` and independent bolt providing a strong and durablestructure The above, and various otherA objects and advantages ,ofthisf inventionwill be in part described, and in` part understood, from the4 following description ofthe present `preferred embodiment,` the same being illustrated inthe accompanying. drawings where-A 111 r` l v Figure 1 is atop plan view of the chassis of a motor vehicle showing the `improved driving and steering mechanism of vthis invention applied` thereto.

Figure 5 is a horizontal section `through the fifth wheel structure taken on the line 5-5 of Fig.4. L Figure 6 is alongitudinal section through thefront end of the vehicle taken substan tially on'the plane indicated by the line H,

and llooking toward the right handside of the structure.

Referring to these drawings,10 designates the frame of a motor vehicley which may be gear and the brake ap# of any approved construction and desigin,

and which in the present instance is shown elongated yrectangular form. The frame 10 is supported at its rear end uponV a transverse ,dead rear axle 11 upon the opposite ends of which are mounted rear carrier Wheels 12 of the usual construction. lach carrier wheel 12 is provided at its inner side with a drive gear wheel lwhich meshes with a pinion 14 mounted upon 'the end of a drive shaft 15. A housing 16 en closes the drive shaft `which is provided intermediate its ends with differential gearing 17 lof any approved type. The housing 16 is supported in any suitable manner upon one of the rear wheels;V

the rear axle'll and is preferably arranged above the same to vprovide ample clearance beneath the axle.` From thev differential gearing 17, aV drive shaft 18 projects forwardly and upwardly into the frame 10, and has bearing near its forward end in the rear wall of a transmission casing 19,and is provided within the casing 19 with aspur gear wheel 20. y y i Y, Arranged in the casing 19 and extending transversely across the frame y10 is a supporting shaft 21 having slidably mounted spur gear wheels 22 and 28 thereon which are connected together by a yoke 2st adapted to slide the gearwheels 22 and 23 `simultaneously and hold the same in suitably spaced-apart relation from the opposite sides i 1GOl to operate the handle 28 and shift the yoke 24 in the desired direction to engage one of the gear wheels 22 or 23 with the-driving mechanism. The hand lever 28 may be shifted in an opposite direction to change the relation of the gear wheels 22 and 23 with respect to the driving mechanism.

The motor vehicle may be manually steered by means of the wheel 62. If, however,'it is desired to turn the `front axle 67 byv power, it is only necessary to operate the handle 4l to shift the yoke 5l and engage one of the gear wheels 49 or 50, dependent upon the direction in which the axle 67 is to be turned, to connect the steering shaft 57 to the transverse shaft 36 and thus drive the steering post 6l in the desired direction.

The front drive shaft 44 rotates at all times, and when it is desired to connect the front wheel transmission means to the drive v shaft 44, it is only necessary to move the clutch pedal 86 forwardly and close the normally opened clutch 45. When this is done, the front wheels are thus power-driven as well as the rear wheels. The advantage of this construction and arrangement is that when the vehicle is .turned upon a relatively short radius7 the front wheels may be driven in order to turn the vehicle. By driving the front wheels in this manner, the power this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

I claim:

In a motor vehicle the combination of a rectangular frame, a drive shaft in said frame, front and rear wheels, manually controlled steering means for the front wheels, a transmission mechanism disposed between the drive shaft andthe rear wheels, a fifth wheel mounted on the forward end of the frame, a driving axle carried by said fifth wheel, forwardly extending shafts connecting the transmission mechanism and said driving axle, means adapted to actuate said transmission mechanism for imparting driving power to said driving axle, and manually controlled means mounted upon the forward end of the frame -for regulating the connection between the forwardly extending shafts and the driving axle.
